Convert a 1-dimensional indexed vector of real spherical harmonic coefficients to a three-dimensional array.
call SHVectorToCilm (vector, cilm, lmax, exitstatus)
vector : input, real*8, dimension ( (lmax+1)**2 )
: The input 1-D indexed array of real spherical harmonic coefficients.
cilm : output, real*8, dimension (2, lmax+1, lmax+1)
: The 3-D arrary of output real spherical harmonic coefficients.
lmax : input, integer
: The maximum degree of the output coefficients.
exitstatus : output, optional, integer
: If present, instead of executing a STOP when an error is encountered, the variable exitstatus will be returned describing the error. 0 = No errors; 1 = Improper dimensions of input array; 2 = Improper bounds for input variable; 3 = Error allocating memory; 4 = File IO error.
SHVectorToCilm will convert a 1-dimensional indexed vector of real spherical harmonic coefficients to a three-dimensional array. The degree l, order m, and i (1 = cosine, 2 = sine) corresponds to the index `l**2+(i-1)*l+m+1.
